Re: Etnaviv support in Mesa

Gallium has code that allows gallium drivers to be used with the dri
interface. X uses that dri gallium code. It makes gallium drivers act
like dri ones.
I believe all you need is EGL and not GLX if you are using GL ES.
Though as soon as any software you are using requires GLX...
I am not entirely sure if etnaviv uses llvm so you can perhaps leave
that out below.

Here is a mesa config that can run X with OpenGL ES (so all the flags you need):

  ./configure --prefix=/usr \
    --sysconfdir=/etc \
    --with-dri-driverdir=/usr/lib/xorg/modules/dri \
    --with-gallium-drivers=etnaviv \
    --with-dri-drivers= \
    --with-egl-platforms=x11,drm,wayland \
    --with-sha1=libgcrypt \
    --disable-xvmc \
    --enable-gallium-llvm \
    --enable-llvm-shared-libs \
    --enable-shared-glapi \
    --enable-egl \
    --enable-glx \
    --enable-glx-tls \
    --enable-gles1 \
    --enable-gles2 \
    --enable-gbm \
    --enable-dri \
    --enable-texture-float \
    --enable-opencl --enable-opencl-icd \
    --with-clang-libdir=/usr/lib
